Proceedings of the Twenty-Ninth International Joint Conference on Artificial Intelligence, 2020 We propose a logic of directions for points (LD) over 2D Euclidean space, which formalises primary direction relations east (E), west (W), and indeterminate east/west (Iew), north (N), south (S) and indeterminate north/south (Ins). We provide a sound and complete axiomatisation of it, and prove that its satisfiability problem is NP-complete.

Localisation of defects with time and frequency measurements using pulsed arrays [PDF]
, 2014 The frequency dependent directivity of the periodic permanent magnet transducer is to used extract information about the position of any discontinuities present in a sample. Two approaches are used; narrowband excitation, and broadband pulsed generation.

Rectangular Antenna Array Optimization using Wind Driven Optimization
Algerian Journal of Signals and Systems, 2016 Antenna arrays are considered as important type used today for long distance communication with a very high gain. The design of such antenna depends on parameters and desired behavior performing the task, this project handle the application of a new ...

Changing Direction on Direction of Fit [PDF]
Ethical Theory and Moral Practice, 2012 In this paper, I show that we should understand the direction of fit of beliefs and desires in normative terms. After rehearsing a standard objection to Michael Smith’s analysis of direction of fit, I raise a similar problem for Lloyd Humberstone’s analysis.

After direct manipulation---direct sonification [PDF]
ACM Transactions on Applied Perception, 1998 The effectiveness of providing multiple-stream audio to support browsing on a computer was investigated through the iterative development and evaluation of a series of sonic browser prototypes. The data set used was a database containing music.

Directed triangles in directed graphs
Discrete Mathematics, 1992 The authors show that if each vertex of an oriented graph \(G_ n\) has indegree and outdegree at least \(n/t\), where \(t=2.867\dots,\) then \(G_ n\) contains an oriented 3-cycle.

Proceedings of the 1st Annual ACM Symposium on Computational Fabrication, 2017 The goal of display and screen manufacturers is to design devices or surfaces that maximize the perceived image quality, e.g., resolution , brightness, and color reproduction. Very often, a particular viewer location is not taken into account, and the quality is maximized across all viewing directions.

Stepped-Tube Backside Cavity Piezoelectric Ultrasound Transducer Based on Sc0.2AI0.8N Thin Films
Micromachines, 2023 This paper presents a novel piezoelectric micromachined ultrasonic transducer (PMUT) with theoretical simulation, fabrication, and testing. Conventional methods using a PCB or an external horn to adjust the PMUT acoustic field angle are limited by the ...

Modeling the directivity of parametric loudspeaker
, 2012 The emerging applications of the parametric loudspeaker, such as 3D audio, demands accurate directivity control at the audible frequency (i.e. the difference frequency). Though the delay-and-sum beamforming has been proven adequate to adjust the steering
